.. •- • TRANSLATION FROM GERMAN Item #l 12-21-53 Mr. ALOIS PIWETZ 164 Halsted Str. New Jersey, U. s. A. Dear Mr. PIWETZ, Your brother will probably have communicated with you about me as we became acquainted with/ each other at a construction job. I told him a few things about inventions or utilization. Dear Mr. PIWETZ, be not angry with me because I am now turning to you. I hesitated such a long time as my wife does not wish to go abroad. Enclosed I am sending you 2 inventions, that is, ideas and I leave it to your own ( power of judgment whether one or both, or none of these inventions is suitable. If one seems to be profitable to you, you should apply for a patent in your own name as the best possible way and enter 'for me and for yourself 45%each of the ·net profit and 10% for your brother. I am giving you entirely a free hand, as you will undoubtedly try to attain the greatest possible profit. And now, dear Mr. PIWETZ, I am talcing the liberty of telling you something about 8ll invention which the entire world wants to have. (I am only writing the most important f acts.) Before the war I intended to make a toy, something which f lies, and purely accidentally I di scovered a hitherto unknown aerodynamic law. I experimented further. I improved and informed several comrades. They were enthused and emigrated to South America . There they tried it on their own responsibility. People were killed and they f ailed t o perfect the incomplete invention. They approached me again. As they were only artisans, 'these flying machines were, of course, built primitively. The first experiments to fly with a motorcycle motor attained the result of 250-300 km. Not bad for the years 1938-391 With a powerful motor they then flew 2600-2800 km. (hour kilometers). «--rtrt\ <' ""J,, 4rfp B'I: ~~tC/}t?tCt-/ 6. NEtl//A!IS r1: :J ;11/'( G !9 7 1-/ --,)) COPIES DESTROYED 2 'i O NOV 19 1Sci4
